Application fi1ed 0ctober 30, 1980, Serial No.

Chemicalpicture-telegraphequipments are mostly in need of a moistening device for the picture support which consists of paper with a chemical preparation or emulsion thereon. For moistening the paper according to the prior art, it has been customary to pull the paper prior to use by hand through a dish containing liquid, or else, if the paper was fed from a storage spool, the paper was automatically passed underneath a, roller through fed forward. It

has also been suggested to guide the paper .over a split tube which was in connection with a liquid-container. But in all of these devices the paper becomes moistenedv either irregularly or unduly,-.with the result that the signal, pictures or the like to be trans-, mitted become blurred, and that also a blurred picture is reproduced.

"The present invention aims to eliminate this drawback by guiding the picture carrier or support over a roller, spool, or equivalent device adapted to spread the moistening liquid. In this arrangement, the roller may move inside the li uid over part of its circumference and there y supply an always constant and properly proportioned volume of liquid to the support guided over" another part of the circumference.

Another improvement may be obtained by surface of the roller with a porous absorptive material such as burned or baked clay. Another embodiment would be to store the liquid in the interior of the roller and provide perforations for the outflow of the liquid towards the roller surface. In this".

- scheme it is also desirable to cover the surface of the roller with a cylinder consisting of baked clay in order to thus prevent the paper from being moistened more strongly in some places than .in others.

The principle of the invention is illustrated by the accompanying drawin wherein Figs. 1+3 illustrate various embodiments of the 492,192, and in Germany September 20, 1929;

4 is pressed against the cylinder 2 by thev presser roll 5 and is then guided over the inker blade 7. Opposite the inking blade or edge 6 is therecorder electrode 12 which is in contact engagement with the paper .6.

The paper is here preferably moistened from the rear. The uniformly with the l quid so that it will also moisten uniformly. the paper coming in contact therewith. i

In the embodiment shown byway of ex' ample in Fig. 2, the roller or cylinderi8 consists at least superficially of an absorbent material, say, porous clay. The strip of paper 6 is here conducted preferably over a relatively large circumference of the roller, the time of contact and thus the degree of moistening 'in each instance being exactly measurable or controllable by also making the rolls -9 and 10 adjustable.

Fig. .3 shows an "embodiment in which the liquid is located in the interior of the cylinder the inner shell 11.0f which consists of im-' openings 13 is able to become uniformly distributed overthe coat of clay and thus be imgarted' to the, paper 6.

ther modifications and changes may suggest themselves to those skilled in the art to which the invention relates, and I, therefore, believe myself to be entitled to make and use any and all of such modifications as fall fairly .within the spirit and scope of the hereinafter appended c aim.

r0112 becomes moistened Having now described 111 invention, what I claim and desire to secure y Letters Patent is the following:

In an apparatus for receiving pictures on moistened chemical records, a container roll having a filling of chemical moistening ma.- terial therein, a porous absorptive material on the periphery of said container, means for moistening said material with the liquid contained within said'container, and means for fiassin a record strip over approximatel alf o the periphery of said container to in contact with said material, whereby the record strip is moistened by the chemical solution.

In testimony whereof I aflix my signature.
